Title: Method of curing photocurable composition
Inventor: SUGITA SHUICHI
IPC: C08F2/50
Filed: 1995-02-21
Abstract: PURPOSE: To completely photocure a photocurable composition at good efficiency in air by irradiating the composition with light while keeping the composition in the state in which a liquid immiscible with the composition intervenes between the composition and the air layer. CONSTITUTION: A photocurable composition consisting essentially of a polymerizable unsaturated compound (e.g. pentaerythritol triacrylate) and a photopolymerization initiator is prepared. The photopolymerization initiator is suitably an initiator sensitiye to visible light of 400nm or more or infrared light and is exemplified by an initiator prepared by combining a cationic dye of the formula with tetrabutylammonium n-butyltriphenylborate being a boron- based catalyst. This composition is cured by irradiating it with light while it is kept in the state in which a liquid (e.g. water) immiscible with it intervenes between it and the air layer. According to this process, the inhibition of photocuring due to the oxygen present in air can be effectively prevented.

Abstract: PURPOSE:To prolong the life of a disk and to simplify the structure thereof so that the disk is inexpensively obtd. by laminating a light interference layer and a magnetic recording film having a nitrogen-contg. layer on the surface on a plastic substrate. CONSTITUTION:An underlying film (light interference film) 2 and a perpendicularly magnetized film 3 are successively laminated on the optically transparent plastic substrate 1 and the nitrogen-contg. layer 4 is provided on the surface of the perpendicularly magnetized film 3. As a result, the corrosion resistance to water and oxygen increases on the surface of the recording film 3 and since the nitrogen is not contained in the substrate 1 side surface of the recording film 3, the magneto-optical characteristics and perpendicular anisotropy are improved and high C/N is obtd. The inexpensive magneto-optical disk having high reliability and simple structure is thereby obtd.

Title: Optical fiber gyro
Inventor: MIMURA MICHIHIKO
IPC: G01C19/72
Filed: 1989-02-15
Abstract: PURPOSE:To stabilize a phase difference signal and to suppress an offset by providing the electronic circuit of the gyro with a detector, control signal generating section, correcting section and modulation control section. CONSTITUTION:The detector 22 of the electronic circuit 20 of the gyro extracts plural higher harmonic components contained in a light quantity signal A and the control signal generating section 23 forms 1st and 2nd control signals C1, C'2 in accordance with the higher harmonics of the second and higher orders among the higher harmonic components. The correcting section 25 outputs the phase difference signal B' corresponding to the angular speed of an input axis in accordance with the odd order higher harmonics of the 3rd or higher orders among the higher harmonic components and the 1st control signal C1. The modulation control section 27 controls a phase modulator 7 so as to maximize the odd order higher harmonics in accordance with the 2nd control signal C'2. Since the pickup noises by detection are not included in the phase difference signal by this constitution, the offset is hardly generated even if the modulation degree is so controlled as to maintain specified sensitivity in various environments. The fluctuation in zero point is thus suppressed and the stable zero point output is obtd.

IPC: H01J37/317
Filed: 1992-01-24
Abstract: PURPOSE:To prevent electric discharge by maintaining the insulativeness inside of an air exhausting pipe installed between a high voltage part at a high potential and a surrounding part at the reference potential. CONSTITUTION:One end 12a of an internal cylinder 12 is connected with a casing 102 of a high voltage part 104, while the other end 12b is not connected with a surrounding part 100 but put buoyant in the neighborhood of an air exhausting hole 136' so as to form an uncontinuous part. One end 14a of an external cylinder 14 is connected to the casing 102 in a single piece structure with the end 12a of internal cylinder 12, while the other end 14b is connected to the surrounding part 100. Because the internal cylinder 12 does not directly connect the high voltage part 104 to the surrounding part 100, no high voltage is impressed, and eventual drop of insulativeness does not involve the risk of generation of electric discharge there. A high voltage is impressed on the external cylinder 14, but the inner wall 14c, in particular the innermost part therein, is not exposed to the exhaust gas to any larger extent, so that contamination with oil mist, etc., is lesser to preclude drop of the insulativeness, and there is no risk of generation of electric discharge.

Abstract: PURPOSE:To enable to stop without rotating a wiper motor to the normal stopping position at a high load time by forming a plurality of notches for interrupting the current flowing path to the motor on the circumference of a flat cam which rotates synchronously with the rotor of the motor. CONSTITUTION:A plurality of notches 12 set at 5-15 deg. are formed in addition to a notch 9 for interrupting an electric circuit as an inslating state of contacts 6, 7 on a cam 4 of a flat plate shape which rotates synchronously with a rotor 5 of a wiper motor. When a switch 1 is stopped at the stopping position 2 at the normal load time, a blade is overdriven at the notch 12 due to the inertia of the rotor 5 to be stopped at the prescribed stopping position of the window frame lower side, and stopped at the notch 12 due to the small inertia at the high load time such as that glass is semidried. Accordingly, it can be immediately stopped due to the OFF of the switch 1 at the overload time, thereby preventing the motor from burning out.

Abstract: PURPOSE:To stabilize air-fuel ratio by arranging a solenoid valve in a path communicating between a canister and an intake path in the downstream of a throttle valve, and resetting correction variables to ineffective values which substantially cause no variation on the fuel supply quantity, as required, when the solenoid valve is switched. CONSTITUTION:A fuel tank 25 communicates through a purge path 26 arranged with a canister 28, with an intake path 12 in the downstream of a throttle valve 18.
